Made from BK7 material, which has transparent range from 330-2100nm. The refractive index is 1.5168 at 587.6nm. The BK7 window has good performance over visible and near IR spectrum for most application.

Non-Polarizing Plate Beamsplitters can be used with high power laser. When using beamsplitter plates, it is important to bear in mind that the two partial beams travel different optical paths. And the optical paths depend on the incident angle and the thickness of plates.

LBO(Lithium Triborate LiB305) is a newly developed nonlinear optical crystal.It is unique in many aspects,especially its wide transprency range,moderately high nonlinear coupling,high damage threshold and good chemical and mechanical properties.
